List data in view

List every dataset the session's viewport offers (layers, tables, documents, scanned maps): the same list the Ploti map shows for this view and zoom, unranked, as titles. Use it when find_data doesn't find what you need or you are unsure it found the right thing. Rows (type, title, id, and a lock with what opens it) come grouped by place: the view's own places first, then state and national data. The header counts everything in view by place, category and type. Narrow it with types or categories to what the question needs, then page with offset until no next offset is given; leaving them out lists everything, which in a dense view runs to many pages. Pass ids from the rows to read those datasets in detail: description, category and how to read each. Then check a few rows (tools.schema, SQL) or a document's sections before using one.
